This 'all-in-one' computer system was released by Polo Microsystems in 1984. It was marketed as a machine that contained everything you needed to run a small office - including items that other computer manufacturers would sell separately such as monitors, disk drives, a printer, and software.

It featured two microprocessors: an Intel 80188 to run DOS and PC-compatible software; and a Zilog Z80 to allow it to run CP/M software.

It also included a modem to allow it to dial-up to online services. One notable feature was the button on the upper-right of the keyboard. This placed it into a low-power 'sleep' mode from which it would wake periodically to dial-up to the user's mail service. If any unread messages were found, the Polo would return to sleep mode with a flashing LED to alert the user to their new mail.
